Short answer

Designers should consider how to integrate and support post-purchase circularity, particularly by appealing to social influences and perceived ease of action, and by recognizing the value of second-hand adoption as an indicator of sustainable intent.

Evidence
Moderate effect

Consumers who actively choose second-hand fashion products demonstrate a greater propensity to engage in sustainable practices after the initial purchase, such as reusing, repairing, or recycling. This sustainability research insight is drawn from a 2025 study published in Discover Sustainability. Using Quantitative survey and statistical modelling with 500 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should consider how to integrate and support post-purchase circularity, particularly by appealing to social influences and perceived ease of action, and by recognizing the value of second-hand adoption as an indicator of sustainable intent.

Key Findings

  • 01Consumers who purchase second-hand fashion are more likely to engage in sustainable post-purchase activities.
  • 02Four distinct clusters of fashion consumers were identified based on their post-purchase behaviours.
  • 03Attitudes have a minor influence on repairing and donating fashion items, while social norms and perceived behavioural control are more significant.

Application

Design takeaway

Designers should consider how to integrate and support post-purchase circularity, particularly by appealing to social influences and perceived ease of action, and by recognizing the value of second-hand adoption as an indicator of sustainable intent.

How to apply

When designing fashion products or services, consider how to facilitate reuse, repair, and recycling. Market these features by highlighting what others are doing (social norms) and how easy it is to participate.

Project actions

  • 01Consider how your design can encourage users to extend the life of a product.
  • 02Investigate the social and practical barriers to sustainable product use and disposal.

Method & Evidence

AimWhat factors influence consumers' intentions to reuse, repair, and recycle fashion textile products?
MethodQuantitative Survey and Statistical Modelling
ProcedureA survey was administered to 500 residents in Budapest, Hungary. Data was analyzed using clustering techniques and structural equation modelling based on the Theory of Planned Behaviour.
Sample500 participants
ContextFashion textile product consumption and post-purchase behaviour.

Variables

IV["Preference for second-hand fashion products","Attitudes towards sustainable post-purchase behaviours","Social norms related to sustainable post-purchase behaviours","Perceived behavioural control over sustainable post-purchase behaviours"]
DV["Intentions to reuse fashion textile products","Intentions to repair fashion textile products","Intentions to recycle fashion textile products"]
CV["Demographics (age, gender, income)","Location (Budapest, Hungary)","Type of fashion textile product"]

Strengths & Limitations

Strengths

  • +Utilizes a robust theoretical framework (Theory of Planned Behaviour).
  • +Employs advanced statistical methods (clustering and SEM) for in-depth analysis.
  • +Investigates a critical aspect of the circular economy: post-purchase behaviour.

Limitations

The findings are specific to fashion textiles and may not apply to other product categories. The study's focus on Budapest might not reflect global consumer attitudes.

Reliability & validity

The study's reliability could be enhanced by using validated scales for TPB constructs. Validity is supported by the use of SEM, which models relationships between latent variables, and by the identification of distinct consumer clusters.

Think critically

How can designers create products and systems that not only encourage initial sustainable purchasing but also actively support and incentivize sustainable post-purchase behaviours, considering the influence of social norms and perceived control?

05

Design Principles

"Leverage existing sustainable behaviours and social influences to promote circular economy practices."

Understanding this consumer segment is vital for developing targeted strategies that promote circularity in the fashion industry. It highlights an existing behavioral pattern that can be leveraged to encourage broader adoption of sustainable post-purchase actions.

06

What This Means for Your Design

People who buy used clothes are more likely to do good things with their clothes afterwards, like fixing them or recycling them. What their friends think and whether it's easy to do these things matters more than just liking the idea.

How to use in your project

  • 1.Use this research to justify investigating consumer behaviours related to product longevity and disposal in your design project.
  • 2.Cite this study when discussing the importance of social norms and perceived behavioural control in influencing sustainable design choices.

Paragraph starter

This study by Kemi and Zilahy (2025) highlights that consumers who engage with second-hand fashion products tend to exhibit stronger intentions for sustainable post-purchase behaviours, such as reuse, repair, and recycling. Their research indicates that social norms and perceived behavioural control are more influential drivers of these actions than personal attitudes, suggesting that design interventions should focus on facilitating these aspects to promote circularity.
